This is a genuinely well-built barrier moisturizer, not a marketing fluff bomb.

The efficacy score is high because the formula stacks multiple evidence-backed barrier lipids (ceramides, cholesterol, phytosphingosine, fatty acids), plus strong humectants like glycerin, betaine, panthenol, and several forms of hyaluronic acid across the ingredient list. It loses a little credit because the ceramides and HA are not all at the very top of the INCI, so this is more of a robust support formula than a concentrated treatment, but the base is still excellent for hydration and barrier repair.
